摘要： A method and system for adapting a CNC machine tool path from a nominal workpiece shape to an actual workpiece shape. The method includes defining a grid of feature points on a nominal workpiece shape, where the feature points encompass an area around the machine tool path but do not necessarily include points on the machine tool path. A probe is used to detect locations of the feature points on an actual workpiece. A space mapping function is computed as a transformation from the nominal feature points to the actual feature points, and the function is applied to the nominal tool path to compute a new tool path. The new tool path is used by the CNC machine to operate on the actual workpiece. The feature points are used to characterize the three dimensional shape of the working surface of the actual workpiece, not just a curve or outline.

摘要： An automated method for discovering features in a repeatable process includes measuring raw time series data during the process using sensors. The time series data describes multiple parameters of the process. The method includes receiving, via a first controller, the time series data from the sensors, and stochastically generating candidate features from the raw time series data using a logic block or blocks of the first controller. The candidate features are predictive of a quality of a work piece manufactured via the repeatable process. The method also includes determining, via a genetic or evolutionary programming module, which generated candidate features are most predictive of the quality of the work piece, and executing a control action with respect to the repeatable process via a second controller using the most predictive candidate features. A system includes the controllers, the programming module, and the sensors.

摘要： A method for programming a three-dimensional (3D) workpiece scan path for a metrology system comprising a 3D motion control system, a first type of Z-height sensing system, and a second type of Z-height sensing system that provides less precise surface Z-height measurements over a broader Z-height measuring range. The method comprises: placing a representative workpiece on a stage of the metrology system, defining at least a first workpiece scan path segment for the representative workpiece, determining preliminary actual surface Z-height measurements along the first workpiece scan path segment, and determining a precise 3D scan path for moving the first type of Z-height sensing system to perform precise surface Z-height measurements. The precise 3D scan path is based on the determined preliminary actual surface Z-height measurements. The precise 3D scan path may be used for performing precise surface Z-height measurements or stored to be used in an inspection program.

摘要： An electric motor includes at least one first brush and at least one second brush, which are arranged in a stationary fashion and arranged to contact a commutator that rotates with a rotor. The commutator includes at least one cylindrical section with a circumferential surface on which a plurality of segments are arranged with insulating sections interposed between them. In order to detect the rotating speed and position of the rotor, the motor includes brushes with asymmetric circumferential widths or angles or a stator with an uneven magnetization. The motor is arranged to detect only one signal when the rotor rotates for an angle between two adjacent segments.

摘要： The invention relates to a method for automatically generating several electrical pulses using numeric default values, in particular for simulating an incremental encoder for a sequential, digital counting of linear or angular displacement values using said pulses. The method incorporates a value generator that outputs the default values repeatedly within each first cycle time, calculation and control means that detect the default values in a cyclic manner and a pulse switching interface that has one or more outputs for the pulses. The program and/or circuitry of the calculation and control means are designed:—for detecting the respective current default value and for determining a differential value from the current and preceding default value or incremental value for each first cycle time, said value having been previously counted in ascending or descending order, according to preceding default values,—for converting the differential value into control signals for the pulse switching interface within several second cycle times, whose total duration does not exceed the first cycle time of the value generator,—and for measuring the number or frequency of the pulses or pulse edges, according to the respective differential value.

摘要： The invention provides a servo motor encoder in which signals are output via signal lines and output terminals which are used in common. Incremental signals A, B, and Z and servo motor magnetic pole position detection signals UE, VE, and WE are switched by a multiplexer so as to output these signals via a common line driver. Alternatively, two line drivers are selectively activated and inactivated so that incremental signals and servo motor magnetic pole position detection signals are output via common signal lines. In any modes, signals can be carried via a less number of signal lines.

摘要： Positioning errors of a moveable machine member are reduced by compensation for cyclic errors attributable to anomalies of a position transducer. Compensation values are produced which are unique only within the pitch of transducer measurement and are applied to correct the representation of measured position produced by the transducer. Positioning errors not attributable to the position transducer are corrected by compensation of position commands using compensation values associated with fixed calibration points. Use of both compensations is effective to eliminate residual errors in position correction which arise from use of calibration data created without correction of transducer cyclic errors.
